Polybrominated diphenyl ethers (PBDEs) are synthetic chemicals that are added to a variety of consumer products as flame-retardants. The ubiquitous nature and endocrine disrupting properties of PBDEs are a public concern. A pilot study was performed to investigate whether in utero PBDE exposure, as measured in maternal hair, is associated with genitourinary tract malformations in male infants. In addition, we compared PBDE levels in maternal and infant hair and used segmental analysis to investigate how PBDEs varied along the shaft. Preliminary results suggest a trend toward an elevated PBDE body burden in mothers whose infants were born with genitourinary tract malformations; this was significant for some PBDEs. The sum of PBDEs (ΣPBDEs) in maternal hair did not correlate with infant hair levels; children had significantly greater levels. A significant increase in the ΣPBDEs was observed in distal hair suggesting hair PBDEs may be reflective of both internal and external exposure.
